Hello! Im trying to get pregnant & need advice

Tae

Hello I’m new to this app and I wanted to try something different. I had Flo before and it was accurate for the most part. Me and my bf have been trying for a baby for almost a year, but sadly no luck. I’ve had missed periods but my period has always been irregular. Back in May I had light (bright pink blood, not heavy) spotting but no actual period it lasted only 4 days. For 3 weeks my period was late, I started getting sensitive to smell and could only eat toast. I took 2 pregnancy tests and both came back negative. I made an appointment with my OBGYN and confirmed i wasn’t pregnant. I got my period in June and now it is 12 days late and I’m light spotting again but it’s so light to the point you wouldn’t even notice and I’ve been overly emotional and mild nausea (not as bad as before). Me and my bf did the deed last week of June right around when I was ovulating. I don’t want to get my hopes up and waste money on a pregnancy test but I’m still hoping. I just need some friendly advice.
